EFFECT OF HYDRATED LIME ON AGEING BEHAVIOUR OF BITUMINOUS MASTICS
Influence of the presence of hydrated lime in filler on short- and long-term ageing behaviour of mastics has been investigated using the RCAT device (Rotating Cylinder Ageing Test). Two fillers (limestone and an active one with 25% of hydrated lime) and four bitumen (several pen-grade and origin) have been examined. Short-term ageing 'RCAT163' and long-term ageing 'RCAT90' were linked up on the same sample. Measured characteristics were penetration, R&B, infrared spectra and some selected rheological properties. Hydrated lime improves the sensitivity to short-term ageing by all35% for Venezuelan bitumen 70/100 and by all15% for Venezuelan bitumen 50/70 and for bitumen 35/50 from the Middle East. Lime almost does not modify it for bitumen 35/50 from Venezuela. For long-term ageing, hydrated lime improves the ageing sensitivity by about 33% in case of higher pen grade bitumen (50/70 or 70/100). There is almost no effect or a slight increase in long-term ageing susceptibility for the harder bitumen (35/50). Some other improvements by lime addition are also stated.
